I am using the original GPCam mono. It displays and functions using Altair capture and also using SharpCap 3.0 However having loaded Sharpcap 3.1 and licenced it for Pro, the camera does not appear on the camera list. I have tried this using two different laptops, one Windows 7, the other Windows 10 but with the same results. Rescanning for cameras, using different USB ports and different USB leads makes no difference. Any helpful suggestions will be gratefully received.

try installing the latest AltairCapture on the machine as this will update the drivers for the camera which may help. If you have never installed AltairCapture on a PC then the drivers for the camera won't be available and if you have old versions then maybe the newest SharpCap will not see the camera.

Hi Robin,
Thank you for your suggestion. I tried this approach this morning so am using the latest versions of both SharpCap and AltairCapture, sadly with no effect. I'm afraid I've exhausted my aged meager knowledge.
Cheers

If you still have SharpCap 3.0 on one (or both) of these machines, does SharpCap 3.0 still detect and work with the camera correctly? (You can re-install SharpCap 3.0 if you have taken it off, it will be quite happy with SharpCap 3.1 still on the machine)

Can you post the SharpCap log from one of the machines - plug in the camera, run SharpCap, check the cameras menu and then goto Help->Show Log in the menu and copy all the log text.

Also may be worth trying going back to an older version of SharpCap 3.1 (try 3.1.5174 which was before the latest Altair SDK update) - let me know if that works.

Hi Dave,
Thank you for you investigation. I tried 3.1.5174 as you suggested and that was fine. I see you have taken matters further. So I guess I'll settle for version 3.1.5181 as that seems to detect the GPCam ok. I am hoping to get an Altair Hypercam later this year (not sure which one yet) but I'm sure that will be fine on SharpCap with no problems.
Thanks for your help.
Cheers
Peter
